Can energy storage improve solar and wind power?

With the falling costs of solar PV and wind power technologies, the focus is increasingly moving to the next stage of the energy transition and an energy systems approach, where energy storage can help integrate higher shares of solar and wind power.

Why are solar and wind technologies getting cheaper?

Policy and shifting attitudes toward climate change are an important driver of this transformation, but the underlying enabler is cost: solar and wind technologies keep getting cheaper on a per MWh basis, driven by scale and marginal technological improvements.

How can energy storage technologies help integrate solar and wind?

Energy storage technologies can provide a range of services to help integrate solar and wind, from storing electricity for use in evenings, to providing grid-stability services.

What are energy storage technologies?

Informing the viable application of electricity storage technologies, including batteries and pumped hydro storage, with the latest data and analysis on costs and performance. Energy storage technologies, store energy either as electricity or heat/cold, so it can be used at a later time.

Are wind turbine prices falling in China?

While wind turbine prices in China have been falling, they have increased elsewhere since 2020. BNEF’s turbine price index shows component costs coming down again in 2025, but manufacturers are keeping prices high to improve margins.

Are battery electricity storage systems a good investment?

This study shows that battery electricity storage systems offer enormous deployment and cost-reduction potential. By 2030, total installed costs could fall between 50% and 60% (and battery cell costs by even more), driven by optimisation of manufacturing facilities, combined with better combinations and reduced use of materials.
